PolyK Advanced Film Capacitors

PolyK is one of few companies with direct expertise and in-house facilities to vertically integrate the film capacitor supply chain. Our expertise include polymer science (material formulations), ultrathin film R2R production (extrusion, solvent casting, and orientation), morphology, thermal, high voltage, and dielectric characterization of film and capacitors, capacitor design, modeling, winding, impregnation, and test -- all at PolyK. This helps us to address the development from an interdisciplinary point of view, not only from materials or capacitor.

We have demonstrated that several widely held opinions are incorrect even though they are very popular in the film capacitor industry and in many peer-reviewed publications due to our interdisciplinary expertise.

We never work on exotic materials, we only work on practical solutions with both cost and technical advantages.
